DUST-PREVENTIN Gr EMPTYING DEVICE FOR FUSTBINS.

Application filed January 9, 1925, Serial li /ma am in Germany June 11,1924.

In this known device this latter or the bin is .PIOVlClGCl with a sliding cover whlch 1s coupled with the filled bin prior to its being emptied and must be uncoupled from the emptied bin in order to be able to remove it from the emptying device. The coupling means, or the means for actuating the coupling-members, are arranged, with said known device, below the frame thereof. In our improved construction the cover or lid of or for the bin is connected with levers in such a manner that the closing and the opening of the bin takes place automatically, there being no separate lifting device and no handle or the like for operating acoupling, as is all fully described hereinafter.

ur invention is illustrated by way of exemple in the accompanying drawing. in which Figure 1 is a side view of one form of the improved dust-bin, the filled bin stand ing'upright in the emptying device. Figure 2 is a view taken at right angles with respect to Fig. 1. Figure 3 is a View similar to Fig. 1, the bin being somewhat tilted. Figure 4 I shows the bin completely tilted, i. e. turned upside down. Fig. 5 is also a view similar to Fig. 1 and shows another constructional form of the device; Figure 6 is a view similar to the uppermost part of Fig. 2, butrelating to said modified form. And Fig. 7 is 'a view similar to Fig. 3 (dustbin partly tilted) and relates also to the modification.

, The frame of the device (Figs. 1-4:) consists of two standards it it carrying each a bearing j and being each provided with an upwardly extending curved arm 9. Between the standards it h the cage-like tilting frame is supported by neansof pivots i i the sides of saidcage are denoted with c c. side-frames are connected with each other near their lower ends by a bottom-plate I) intended to receive the dust-bin. (Fig. '2).

Above the dust-bin a hood a. connected with, and carrying, the cover or lid Z. is so, arranged 'asto be, shiftable vertically in.

easily upon this'bottom.

These guide-ways provided in or at the side-mem- 7", the lower ends of which frame membersc c (Fig. 2). Opposite the curved arms g g rectangular theiruppermost horizontal parts with. the

ends of the curved arms 9 g. These are. v

provided at their inner sides withcorre: spo-ndingly curved guide-ribs 7c is Supposing, the movable parts of the device be in the position shown in Fig. 1, the filled dust-bin which is to be emptied is placed on the bottom 6. In this position of,

the dust-bin an annular' space or gap of about 2 or 3 cm. width remains between the upper edge of the bin and the lower edge w PATE T, v OFFICE JULIUs FRANKEN. AND AUGUST VORDENBAUMEN, orGELsnNKIRoHnN;GERMANY, ASSIGNORS TO THEHERM. FBANKEN AKT. ens, 0EGELSENKIRCI-IENQSCHALKE,

(-55 a carrying each a roll 6 and being also con-- nected'withthe upper ends of helical springs are secured to the 1,

at arms 0 c extend upwardly from the standards 7L h andare connected at the ends of,

(Fig. l) of the annular frame a of t he hood.

This frame consistsof twosuperposed rings,

ofangle-iron, as shown in dotted lines in, the top portion of Fig. 1. Thedistance'of said hood parts (a) fromthe bottom-b is, therefore, such that the dustbin .canbe placed The rolls 0 of the pivots a run on projections 8 aflixed to the inner sides of the horizontal members of the rectangular; arms or standards 0 c. The helical springs ff are under tension when the parts in question are in the position shown in F igj2. The shape of the projections s Sissuch that the hood is raised a little when the tilting of the frame 0 Z) 0 commences, but immediately thereafter the hood is drawn down upon the bin by thev springs f f. VVhenthe pivots n n have arrived at the points, Fig. '3, the dust-bin is. completely closed. I y i lVhen the rolls 6 ehave left the projections 8 8, they contact W'iththe inner surfaces or the guide-ribs la whereby the springs f are relieved from the weight of thehood. T

The tilting of the dust-bin is, continued until this latter arrivesiri the position Fig. 4:, but prior thereto the hoodfwith the cover or lid is retained at'a place locatedlso much remote from i the opening receiving" the con-f tents of the bin that the emptying of the bin into that opening is not impeded. The cove'r qse d has a projection cl and the base is provided with a projection t, so that as the profirst the hood with the cover or lid reassumes its place on the bin, then these parts together rise while being turned on and around the pivots c i, and shortly before arriving in the proper vertical position, the hood with the cover or lid is again raised a little so that the above mentioned gap between the upper edge of the dust-bin and the lower edge at (Fig. 1) is again formed, permitting the removal of the emptied bin from the bottomplate 5. The various movementsof the hood with the cover or lid are again caused (al though in the reverse sequence) by the guideribs 74 is, the projections s s, the rolls 6 which co=operate with these projections, and the springs f fwhich holdthe parts 8 and e in contact with one another. In the normal position of the parts (Fig. 1) the springs are again under a certain tension, and the device is ready to receive another filled dustbin.

The device is mounted on a floor or bottom m having below the device the above-mentioned opening through which the garbage is discharged. This opening is normally closed by a plate a hinged at u to said floor or bottom and being connected by bars 2) with certain suitable points of the tiltable frame 0 c which is hinged by pivots y to this frame, the arrangement being such that the discharge opening is opened automatically when the frame 0 0 with the filled dust-bin is tilted or inverted, and is closed automatically when the reverse takes place.

It appears from the foregoing description that the dust-bin is closed automatically when the tilting commences, opened automatically shortly before the emptying, again closed automatically when it is turned into its former or normal position, and finally, again opened automatically when arriving in this position, no other movement of the device being necessary than turning the frame 0 b 0 now in one direction, so as to invert the dust-bin, and then in the reverse direction so as to re-erect it.

' VVhile in the constructional form illustrated in Figs. 1-4 springs form parts of the mechanism, such members are obviated in the .modified form shown in Figs. 57. The

a stationary and the movable'parts of the 'other form, but additional members or frame 'arepractically the same'as in said guide-ledges p 10 with which co-operate the rolls 1* that are'equivalents to the rolls 6 e of the first described constructional form of the device, and the ribsf'q are, practically, equivalents to the ribs 7:; of said form. The guide ledges p p are continuations of the ribs 9 g and'below each'of these ledges is a ledge p, the two ledges p p on either side of the device forming an oblique passage n (Fig. 7 through which the appertaining roll 1" must pass. .At the upper end of each of these passages is a shallow cavity n which forms a rest for the respective roll 1". The rolls r 1" are located in these rests n 13. when the parts are in their normal position, as in Fig. 5. Then the tilting commences, the rolls 1" r-are caused positively to make first a short upward movement so as to get into the sloping passages of n and are then guided by these latter in such a manner that the cover or lid of the dust-bin is moved positively onto the bin in order to close it tightly. Closing the bin positively in this way is to be preferred over springs which are liable to lose their tension by and by.

In the normal position of the parts, before the filled bin is placed into the device, or upon the bottom 7) respectively the hood with the cover or lid is raised (Fig. 5), as in Fig. 1, in order to permit inserting the filled dust-bin thereinto. lVhen then the tilting commences, the cover or lid is caused, by the means described, to move down upon the dust-bin so as to close it, and remains in this position until shortly prior to the frame 0 b c arriving in its inverted position, all as has been described with respect to Figs. 1-4:. The dustbin remains coupled with the frame 0 b 0 until it re-arrives in its normal position in which it can be taken off the bottom I) which then can receive another filled dust-bin.
